Answer:
0.1349
Step-by-step explanation:
Given that:
Sample size, n = 500
20% of 500 ; 0.2 * 500 = 100
p = 0.18 ; n = 500 ; 1 - p = 0.82
P(x ≥ 100) ;
Using the binomial probability relation :
P(x =x) = nCx * p(x)^x * (1 - p)^(n - x
P(x ≥ 100) = 500C100 * 0.18^100 * 0.82^400
P(x ≥ 100) = 0.1349
Answer:
Step-by-step explanation: cos. function theorem
a^2=b^2+c^2-2bc.cos(a)
Answer:
4 and 3 are coefficanta and 12 will be a constant.
if 4 and 3 are being shared by the variable they would be coefficants
if x is not a variable then all the numbers are constants
Step-by-step explanation:
Answer:
14b
Step-by-step explanation:
Answer: There are infinitely many solutions.
Step-by-step explanation:
Given, Two lines, A and B, are represented by the following equations:
Line A: 3x + 3y = 12
Line B: x + y = 4
By comparing to the equations and respectively , we have
Now ,
i.e.
It implies the gives lines are co-incident (linearly dependent).
That means it has infinitely many solutions.
So, the correct answer is "There are infinitely many solutions.".
